三层交换VLAN路由配置技巧详解

在华为三层交换机上创建VLAN，端口划分，三层VLAN接口地址配置，静态路由或是RIP协议配置。跟小编来学习一下配置过程。

　　静态路由配置过程：

PCA:ip address: gw:(VLAN2路由接口IP地址)

PCB:ip address: gw:(VLAN3路由接口IP地址)

PCC:ip address: gw:(VLAN2路由接口IP地址)

S3526A和S352B之间的`互联网段为、24

分配S3526A VLAN4路由接口IP地址为,S3526B VLAN4路由接口IP地址为

　　三层交换机配置

创建VLAN，把PC划到特定VLAN中：

//创建VLAN

[S3526A]vlan 2

//把端口划到VLAN中

[S3526A-VLAN 2]port ethernet0/9 to ethernet0/12

[S3526A-VLAN 2]vlan 3

[S3526A-VLAN 2]port ethernet0/13 to ethernet0/16

[S3526A-VLAN 2]vlan 4

//交换机B的配置：

[S3526B]vlan 2

[S3526B-VLAN 2]port ethernet0/9 to ethernet0/12

[S3526B-VLAN 2]vlan 4

　　配置各台PC的网关地址和交换机之间的网段地址：

//进入VLAN接口配置模式：

[S3526A]interface Vlan-interface 2

//配置三层VLAN路由接口地址

[S3526A-Vlan-interface2]ip address

[S3526A-Vlan-interface2] interface Vlan-interface 3

[S3526A-Vlan-interface3]ip address

[S3526A-Vlan-interface3] interface Vlan-interface 4

[S3526A-Vlan-interface4]ip address

[S3526B]interface Vlan-interface 2

[S3526B-Vlan-interface2]ip address

[S3526B-Vlan-interface2] interface Vlan-interface 4

[S3526B-Vlan-interface4]ip address

　　在二台三层交换机上配置非直连网段静态路由：

[S3526A]ip route-static

[S3526B]ip route-static

[S3526B]ip route-static

查看路由表，查看网络互通情况：

[S3526B]display ip routing-table

Routing Table: public net

Destination/Mask Proto Pre Cost Nexthop Interface

STATIC 60 0 Vlan-interface4

STATIC 60 0 Vlan-interface4

DIRECT 0 0 Vlan-interface2

DIREC T 0 0 InLoopBack0

DIRECT 0 0 Vlan-interface4

DIRECT 0 0 InLoopBack0

DIRECT 0 0 InLoopBack0

DIRECT 0 0 InLoopBack0

　　RlP协议在三层交换机上的配置

1.继续上面的，删除前面配置的静态路由。

[S3526A]undo ip route-static

[S3526B]undo ip route-static

[S3526B]undo ip route-static

2.配置RIP协议：

//交换机B上启用RIP协议

[S3526A]rip

[S3526A-rip]network

[S3526A-rip]network

[S3526A-rip]network

//交换机B上启用RIP协议

[S3526B]rip

[S3526B-rip]network

[S3526B-rip]network

配置完成即可实现网络互通

　　查看路由表，查看网络互通情况：

[S3526B]display ip routing-table

Routing Table: public net

Destination/Mask Proto Pre Cost Nexthop Interface

STATIC 60 0 Vlan-interface4

STATIC 60 0 Vlan-interface4

DIRECT 0 0 Vlan-interface2

DIREC T 0 0 InLoopBack0

DIRECT 0 0 Vlan-interface4

DIRECT 0 0 InLoopBack0

DIRECT 0 0 InLoopBack0

DIRECT 0 0 InLoopBack0

　　查看RlP配置信息如下：

[S3526B-rip]display rip

RIP is turned on

public net VPN-Instance
